PAL expression in C+Z transgenic tubers. (a) PAL mRNA levels detected by RNA gel blot analysis. Ethidium-bromide-stained rRNA bands are shown in the lower panel as loading controls. (b) Quantitative evaluation of hybridisation signals by phosphorimage analysis. Volume means the integrated intensity of all the pixels in the spot excluding the background. (c) Correlation between the anthocyanin content and level of PAL expression in tuber skin. Correlation coefficient r = 0.987931. The relationship is linear at P < 0.05.
